Denville is a town steeped in history, and the Morris County Heritage Commission has identified eight historical highlights:
Saint Francis Residential Community
When the Sisters of the Sorrowful Mother purchased the farm on Pocono Road in 1895, they started making significant changes, beginning with turning the property’s original mansion into a chapel. A year later, they cemented their worldwide reputation by establishing a health resort that later became know as the Franciscan Oaks.

Kitchel House
The Kitchel House on the corner of Ford and Kitchell roads was built in 1770 and the original owner, Abraham Kitchel, Jr., was a New Jersey legislator and Morris County judge.
E. C. Peer General Store
La Cucina was more commonly known as the E. C. Peer General Store in the late 1800s, and was the go-to spot for canal boatmen to stop in for food and supplies.
Peter Cook House
Peter Cook, who established the Reformed Dutch Church in Parsippany, was an early settler in the Rockaway Valley with his Dutch colonial stone home circa 1778. A wing was added in 1808, and the structure remains one of the best preserved homes in town.
Ayres-Knuth Farm
The Ayres-Knuth Farm on Cooper Road has operated since 1803, where corn and rye were grown, and apples harvested. Largely operated by the Ayres (1803-1896) and Knuth (1906-1996) families, the farm was bought by the township in 1996 to preserve as open space.

Second Union School
The Union Hill neighborhood is home to the historic second Union School (the first was destroyed by arson in 1860 and the community rallied to rebuild the current structure). The third Union School opened in 1908, when the second one closed.
Lake Communities
Developers created man-made lakes between 1890 and 1925 to give people an escape from their city life. The lake communities operated as summer resort areas with bungalows and log cabins until they eventually became used year-round.

Jacob Ford House
This circa 1750 house, believed to be built by Colonel Jacob Ford Sr., is situated near the dam of Lake Openaki. The area included a mill and a tavern, the latter of which housed a school on its second floor.
